WARPQBEAM.

isPBCZEECATION forming part of Letters Patent No. 355,823, datedFebruary 1, 1887.

Application filed July 12, 1886. Serial No. 207,837. (No model.)

To @ZZ whom it may concern.-

Be it known that I, ELIHU P. COLLINS, of Lawrence, county of Essex, andState of Mas sschusetts, have invented an Improvement in lVnrpBcnlns, ofwhich the following descrip tion, in connection with the accompanyingdrmvings, is a specification, like letters on the drawings representinglike parts.

lhis invention has for its object to simplify and chonpeu theconstruction of warp-beams used in looms and other machinery whereinwarp is handled upon beams.

Ordinarily the heads of such beams, provided at their centers withnnnulnr flanges to form hubs to embrace the beam, are attached theretoby screws on d wedges, the screws passing through holes in the hubs, thewedges being driven into the space between the hubs and beam.

in accordance with my invention, instead of employing a head having onopen annular hub, I have provided it hood having :1 divided or separablesegmental hub, in order that one part of tho hub-preferably,substantially one hull" of it-mny be moved away from the other half, thesaid movement being preferably accomplished by means of it screw orequivalent adj usting dcvi co.

In accordance with my invention, the two segmental parts of the hub maybe simultaneously clumped upon the beam in any desired adjustedposition, or may be separated to be adjusted upon the boom, andpreferably one or both the segmental sections constituting the hub willhave one or more points or projections to enter the beam, and therebyprevent longitudinal movement of the head upon or with relation to thebeam; but I wish it to be understood that these points may be omitted. lhave also shown the divided hub as provided with short. concavedhearings to aid in the adjustment of the head to inequalities of surfaceof the beam, and so also I have shown the head as provided with anelongated opening, the end of the said opening opposite the rigidsegmental hub mode a fixed port of the head being of it different arethan the fixed port of the hub or of the movable part of the hubattached to the radially-movable plate to be described, such enlarged orelongated opening, when the segmental hubs are separated, affordingspace for the movement of the heads on the beam. To keep thewarp-threads from entering this space I have provided therudiallymovable plate with a projection to span or bridge it when thehead is clamped to the beam.

Figure 1, in elevation and section, shows a warp-beam with my inventionapplied thereto. Fig. 2 is on outside elevation of the head andslide-plate, the central rib of the slide-plate being broken out to showthe spring behind it. Fig. 3 is an inner side view of one of the headsremoved. Fig. 4: is n side elevntion of the sliding plate and itsattached segmental hub removed from the hood; and Fig. 5 is a section ofFig. 2 in the dotted line 6 6, but enlarged chiefly to show the menusfor preventing the movement of the outer end of the slid ing platelaterally from bet-ween the ribs between which it slides.

The beam A, upon which will be wound the yarn or thread, may be of anyusual size, length, and material, it being provided with journals B,driven therein, the said journals being either short rods, as shown inFig. 1, or

of other usual construction.

My improved warp-beam head is composed of a. dish, a, provided at itscenter with an elongated or somewhat oval opening, as 20, the headhaving an attached segments-l or semi-cylindri cal hobo, the hub beingstrengthened, preferably, by a rib, (4?, extended from it outwardly tothe periphery of the dish a, which letter, at its periphery, to securegreateststrength with the least weight of material, is also providedwith a rib or lip, of, the said lips a and a being preferably continuousand formed by casting. The slide 12, having the segmental orsenii'cylindricnl hub b, to co-opera-to with the hub or part c andconstitute a two-parthub to firmly embrace the beam A, is adapted toslide in the space between the ribs c a, the disk at being cut away at10 and 12 (see Fig. 3) to receive projections 13 and 14, extended fromthe rear side of the plate I), to be described, the projection llconstituting a bridging projection having, as herein shown, a point, 3.

The upper pert (see Fig. 3) of the central hole, 20, in the dish a ismade of a greater cirole than thelower part having the point 2, or thesaid hole is elongated or not truly cir color, such constructionenabling the head ato be readily moved or adj nsted on the boom when theplate I) is loosened, as will be described.

When the head has been moved into proper position, the segmental hub bwill be forced inwardly by the adjusting device or screw (2 until thesaid segmental hub and the segmental hub to grasp betweenthem closelythe circular periphery of the said beam, the bridging projection 14 atsuch time resting with its lower edge below the edge of the hole oropening 20 in the head a, and resting against the beam A, thuspreventing the warp-threads from entering the space 15, (see Fig. 3,)which is left be tween the inner edge of the hole 20 in the head a andthe concaved lower end of the plate b, at itsjunction with the flange b.i The flange a of the head a is shown as provided at its interior with aprong, 2, to enter the beam, and with short concaved bearings 16, to actagainst the periphery of the beam and afford a rigid seat for the head.notwithstanding irregularities at the periphery of the beam.

The outer end of the radially-movable plate I) is acted upon by anadjusting device, (Z,

(shown as a screw extended through an ear, (1, and acting upon the endof the plate 12,) rotation of the adjusting device in one directioncausing the plate I) to be forced toward the axis of the beam A, suchmovement of the plate causing the segmental or separable parts a b ofthe hub to be forced snugly against and to embrace closely the saidbeam, the points or projections 2 3 (see Figs. 1 and 2) at such timeentering the beam.

When the screw is moved in the direction to permit the two-part hub tobe separated,in order that the warp-beam head may be removed from thebeam or be adjusted to a different position, it is desirable to providemeans whereby the segmental parts of the hub may be normally keptseparated far enough to permit the head to be moved longitudinally onthe beam without the points 2 3 interfering therewith. To accomplishthis I have herein shown the plate I) as provided with aprojection, 5,(see Fig. 1,) which enters a groove made in the disk a back of the saidplate, a spiral spring, 6, being interposed between the bottom of thesaid groove and the under side of the said lip, the spring actingnormally when its pressure is not overcome by the adjusting device cl tokeep the upper side of the lip 5 against the shoulder 8, constituting apart of the disk to and located at the outer end of the groove whichreceives the spring.

To enable the adjusting device (I to be rapidly turned, its head hasbeen made square to receive ahandle or crank, 0. (Shown by dottedlines.) v

To prevent the lateral movement of the plate b out from between the ribs(6 a", I have provided the ends of the segmental hub I) (see Fig. 4)with prongs 24, one at each side,which prongs enter pockets or spaces 25(see Fig. 1) formed in or at the ends of the segmental part of the huba.

The plate I), at its rear side, near its upper end, is provided with alug, 13, having shoulders at its side, which enter behind lips 26,

'10 between the ribs a the outer end of said space being large enough topermit the entrance of the said lug 13. After the lug 13 has been passedinto the outer end of the hole 10 so that the rear side of the said lugis flush with the back of thehead, the plate bis moved toward the centerof the head, such movement causing the lug to slide behind the lips 26,and at the same time the prongs 24 enter the pockets 25, and thus placedin position the screw d is turned in far enough to keep the lug 13 inengagement with some part of the lips 26, and in this condition theplate I), by any lateral movement of the head a, cannot be pushed orpulled laterally out from between the ribs a I claim 1. A warp-beam headcomposed of a disk having an attached segmental hub provided withpockets 25 and a separate movable plate, I), having apermanently-attached segmental hub, 12, provided with projections 24, toenter the said pocket, combined with means to hold the plate I) inposition, substantially as described.

2. The slotted head or disk (I, having a segmental hub, a, integraltherewith, and lips 26, to constitute guides, and the independent plateb, having a segmental huh, I), and projections 13 14, combined withadjusting devices, substantially as described, to force the saidplate 1) toward the center of the disk a, as set forth.

3. Thewarp-beam head a, having the elongated or oval opening, and asegmental hub,a, combined with a radially-movable slide having asegmental hub provided with a projection, 14, to enter the space 15 leftbetween the inner edge of the enlarged or oval opening of the head andthe inner side of the segmental hub b, to operate substantially asdescribed.

4. The warp-beam head having an opening the edge of which is providedwith short concaved bearings 16 and a segmental hub, a, combined withthe plate b having the hub 71, and with means to hold the plate I) inposition to grasp the beam between it and the hub a, substantially asdescribed.

5. The beam-head a, having a segmental hub, a, pockets 25, opening 10,and lips 26, combined with the sliding plate I), having prongs 24, and ashouldered lug, the prongs entering the said pockets, the said lugengaging the lips, and with means to hold the said plate in position tograsp the beam between it and the hub a, all substantially as described.

Intestimony whereof Ihave signed my name to this speeificati on in thepresence of two subscribing witnesses.
